The above app credits cover both the wtomusic.com intro video segment (appx 16 seconds), and the AirDancer song (appx 2:54). Interesting that even though the music for each segment was created months apart, I ended up using the same set of apps for the music.

For “Echo Delta Motel” (EDM)
I used Novation’s Launchpad app, along with AudioShare and AudioMastering as music apps.
For the video — same as above vidibox (what a super cool app) and iMovie.
